Lateral Mounting Servo Coupling BKH by R + W America


Bellows couplings compensate for slight shaft misalignments while allowing for zero backlash and maintaining a high level of torsional stiffness as well as a low moment of inertia. This makes them ideal for high performance servo motor applications as well as any other requiring a high degree of accuracy in the transmission of velocity and torque. The ability of a single piece bellows coupling to compensate for misalignment is limited in most cases to approximately 0.008” of lateral offset.
